We had a smeg for about a year. Durability wise, there was absolutely no problem with it. Size-wise, however, it was a real challenge. But as I say, durability wise, it's great.
We now have a rangemaster side-by-side. Having lived in so many different parts of the world, the children and I have become rather hooked on having ice in our drinks and it seems to flow on to guests as well. So the rangemaster made more sense for us as I was constantly buying bags of ice every week.

Both the Smeg and the Rangemaster are A-rated energy wise... but if you like the smeg design, I'm sure you'll have no problem with it.
Best of luck
